FTP 5/10 OOP River Decision

[obiedman]

This hand has generated some discussion between my friends and I, and I'm hoping it will do the same here. I think it's a pretty interesting spot where we might get some pretty differing opinions.

Villain is running 25.52/21.23/3.96 (1497) and is definitely a thinking player and a winner. FWIW if I'm going to check the river in this hand, I think it should be to check/fold. However, I'd love to hear any arguments about any lines, from check/calling to check/folding to bet/folding.
